1. Planet Engulfment: Do Stars Eat Their Own Children?
Kandidat-uppsats, Uppsala universitet/Teoretisk astrofysikSammanfattning : Some stars with similar properties to our sun (solar twins) have differ- ent chemical composition than the rest of the solar twins. One explanation might be planet engulfment. Therefore we did a large number of simu- lations where a disturbing star passed a sun and a planet at a distance closer than 100 AU to see how often the planet was engulfed. LÄS MER
2. A differential spectroscopic study of a faint solar twin in the open cluster M67
Kandidat-uppsats, Uppsala universitet/Observationell astrofysikSammanfattning : A solar twin is a star with characteristics very similar to those of the Sun. This is, a Sun-like star. Earlier studies show that M67-1194 is one of the best solar twins found to date. But this star is not exactly like the Sun. LÄS MER
